Best Cash Management Accounts for Emergency Cash

A cash management account (CMA) is a cash account run by a brokerage or robo-advisor rather than a bank. It pays a savings-level rate, often comes with a debit card or checks, and sits one click away from your investments.

It isn't a bank account. That difference matters for how your money is insured, and it's the main thing to understand before opening one.

How a CMA works

The provider takes your cash and sweeps it into accounts at a network of partner banks. Each partner bank insures up to $250,000, so a provider with many partner banks can offer millions in FDIC coverage in total.

Some CMAs, such as Fidelity's, also let you hold your cash in a money market fund instead. It usually pays more, but it's covered by SIPC rather than the FDIC. SIPC protects you if the brokerage fails. It doesn't protect against the fund losing value, although government money market funds are designed to hold at $1 a share.

The main options

CMA or high-yield savings account?

Choose a CMA if you:

• already invest with the same company and want cash next to your portfolio
• hold more than $250,000 in cash and want it insured in one place
• want checking-account features and a good rate in one account (Fidelity)

Choose a high-yield savings account if you:

• want the simplest possible setup from an actual bank
• want the top rate. The best HYSA rates are running a little above most CMAs right now
• deposit cash. Some CMAs, including Wealthfront, have no way to deposit cash

Using a CMA for an emergency fund

CMAs work well for the second tier of an emergency fund, and some can serve as the first tier.

• Wealthfront offers instant withdrawals to eligible bank accounts, 24/7.
• Fidelity gives you a debit card, checks and ATM fee refunds, so the money is available immediately.
• Other CMAs move money by standard ACH in one to three days. See how long bank transfers take and how fast you can get emergency cash.

The catches

Promotional rates end. Boosts usually last three months, or until a fixed date. Compare the base rate.

The rate follows the Fed. Like any savings rate, it can change at any time. If you want a locked rate, look at CDs.

Pick the right option at Fidelity. A Fidelity CMA can hold your cash in the FDIC sweep or a money market fund. At the end of August, the sweep paid about 1.5% a year less than the money funds. Read the Fidelity CMA review before you open one.
